For about three weeks our group has worked on our tank. Over this time the pH had dropped to 6.8 and risen to 7.2. We have kept the pH, ammonia, and nitrate levels as close to what they are supposed to be. We have had days where as much as 19 have died. But still, we have about 280 fish left alive. Today, we changed some water for the second time. It is tedious work because you need to get the replacement water at just the right temp. Then you need to take water out with a pump. That, too, is hard because you need to make sure none of the fish get too near the pump. Then once that is done, you need to put the new water in. It is really heavy! On a whole I enjoy taking care of the trout. My partners and I get along really well.

The PH swings you mention are normal and brook trout can survive in a relatively large PH range. I’m glad to hear that your ammonia levels are near normal, I have one concerned teacher that reports large losses and high ammonia rates which we still have not been able to identify or resolve. Which school are you in? I will note that in the article that you wrote. I’m also glad to hear that you are enjoying teaching TIC to your students and are working together well with your fellow teachers!
